alt-tags key naming

[xynydev]

My mental model of this configuration option was "the default is latest+timestamp, but you can override if you want to", while the alt-tags: name sounds more like "latest+timestamp is the recommended way to tag, but you can swap it out for an alternative method". I'll make an issue about this too.

image-tags: was the name I originally suggested for this key, but I understand that might be confusing, as we also have image-version:.

What do y'all think?

To be completely honest, I came up with that name without going back to the original thread. Now that you brought it up, I don't think image-tags: would have been clear enough. Since we haven't released official documentation for this property, I'm fine with renaming it to something else.

After conversations on discord, we're going to keep this as alt-tags for now and just proceed with working on recipe V2 (#180)
